Fuel injection line ID

[bones1]

I was looking around to see where the engine leaks are all coming from tonight and I found this plastic line behind where you would turn up the fuel. It is kinked closed and just goes in a loop to the other side of the brass fitting?
The truck runs fine, I don't know what this hose does. I do know it shouldn't be kinked closed like that. I think.

Also, looking at the threads on the fuel adjustment screw, do you think it is turned up a little?. Runs real good.

Looks like your FDC is bypassed.... You could take those fittings out and put pipe plugs in there if the kinked hose is a little too cheesy for you...

Yes your bypassed and that line is not used. Yes you are up by thread count. Ever check boost #'s

Never checked boost or EGT #s but think I might get some gauges , actually looked at some Westach gauges this morning. Fuel tank says diesel only.That should have been a clue.
